300g Schwartz Classic BBQ Seasoning £0.47 @ Costco Instore

Costco are selling their 300g Schwartz Classic BBQ seasoning for just 47p. This was found in the Sunbury Costco. Unbelievable deal seeing that all the other seasoning they sell is above £3, even the cashier couldn't believe the price. I assume this is nationwide, not just local, but that's unconfirmed.
